[dlitz@dlitz.net: Whitespace changes extracted from the author's pull request:]
- [9c13f9c] Rename 'IV' parameter to 'nonce' for AEAD modes.
- [4ec64d8] Removed last references to ApiUsageError
- [ee46922] Removed most 'import *' statements
The following changes are included:
- Decoding is a much simpler operation. The internal
logic is based on stream of binary data, and not
on string indexing anymore. Additionally,
decoding used to look like this:
bitmap = DerObject()
bitmap.decode(input_buffer, True)
if bitmap.isType('BIT STRING'):
... proceed with parsing ...
else:
... error ...
Whereas now, it is cleaner and more compact:
bitmap = DerBitString()
bitmap.decode(input_buffer)
Any error condition will lead to an exception.
- isType() method has been removed because of the above.
- Added examples and documentation
- Added support IMPLICIT tags
- Added support for negative INTEGERs
- Added DerSetOf ASN.1 class
- DerObjectID can be initialized from the dotted representation of
the Object ID.
- DerBitString has a new member 'value' to hold the binary
string. The member 'payload' should not be accessed anymore.
- DerObjectID has a new member 'value' to hold the dotted representation
of the Object ID string. The member 'payload' should not be accessed
anymore.
- Added operator += to DER SEQUENCE. Now it is possible to do:
my_str = DerOctetString(b'ZYZ')
seq = DerSequence()
seq += 0
seq += my_str.encode()
- Update to test cases
The test suite contains tests that are disabled because they have the same name
as other tests. Renaming them enables them again.
PKCS1_OAEP_Tests.testEncryptDecrypt1 is updated to work with the new interface
of PKCS1_OAEP.
Typical usage for importing an RSA key:
f = file("ssl.pem")
key = RSA.importKey(f.read())
f.close()
key.verify(hash, signature)
Typical usage for exporting an RSA public key:
key = RSA.generate(512, randfunc)
f = file("ssl.der","w")
f.write(key.publickey.exportKey('DER'))
f.close()
